From bug 59805

[07-Jan-2014 23:31:08] Fatal error: Class 'SolrUpdateWork' not found at
/usr/local/apache/common-local/php-1.23wmf9/extensions/GeoData/solrupdate.php
on line 30
Server: terbium
URL: http://[unknown-host]

It's being run as a maintenance script in cron, but we've no idea what wiki it's being run on. The problem here is that the script is being run on a wiki that doesn't have GeoData installed on it

Database name: XXwiki

Seems accessing MediaWikis php globals is going to be somewhat of a pain to do...

Any bright ideas Tim?

I think this has been fixed for the WMF cluster by the migration to Monolog logging and HHVM's method of notifying the user space handler for fatal exceptions. For example:

bd808$ head -30 fatal.log

Monolog and HHVM take care of this for the WMF. Can be reopened if someone wants to work on adding support to rMWME php-wmerrors as per the original bug report.
